Fullbright
by greeenman999
With Fullbright, the whole world can be lit up on a Fabric client, controlled by a command and an optional settings screen.
What it does
Fullbright adds a toggle that raises the in-game brightness so that dark areas such as caves and nights become readable. The effect is controlled with the /fullbright command, where the strength setting runs from 0 to 10 and defaults to 10. The /fullbright config command opens the configuration screen.
The mod is a client-side only Fabric mod, so only the player's client needs it and servers can run without it. It requires Fabric API and Fabric Language Kotlin, both of which must be installed for it to load. Builds cover 1.19 – 26.1.2, with files published for 27 release versions, and snapshot builds are published as well. The latest Fabric file is 3.2.0-alpha.2+26.1-fabric for 26.1.2, released on 2026-04-02 on the alpha channel. The code is under the GNU General Public License v3.0 only, so it is open source, and the source code and issue tracker are public.

Who it’s for: Players who want better visibility in dark areas on a Fabric client, and anyone who would rather use a command than a texture or resource pack for brightness.
